Hi there,
I’m using Pythonista for couple days and I am fairly happy with.
Nevertheless, I’m trying to import some librairies such as:
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
import sklearn.linear_model

Seems like there are some incompatibility, here under the trace.
Please help,
Oswald

It appears that you have tried to install numpy, perhaps via pip in stash. Or, this tried to install when you tried to install pandas.

Needless to say, on iOS it is impossible to install modules which depend on c, FORTRAN, etc, unless signed by the app (Pythonista) author, which isn’t going to happen. Go into your site-packages folder and delete numpy — you can use the built-in versions of numpy and matplotlib, which are a few versions old, but work fine for most things unless you are someone who works in the bleeding edge.

You likewise cannot install sklearn, scikit, pandas, or anything which is not pure python. You should probably delete anything you tried to install in site-packages, and force quit pythonista.

Thanks for your prompt answer.
